We opted not to support multiple rounds of review for conference submissions, as it's not a common process for conferences. John, I suppose we should remove the Reviewer decision "Resubmit for Review".
Ramón, the Editor decision "Resubmit for Review" has been removed, and submissions should only move into Editing when an "Accept" editorial decision has been recorded. Is there an "Accept" in place?

Corrected -- the extra option for reviewer recommendations has been removed. Ramón, were you able to double-check whether the submission that moved into "In Editing" had an Accept editor decision recorded?

That's as it should be; if the last decision was "Revisions Required", the submission should still appear in the Review queue, pending an author revision. When the author revises, the Director can come back and record an Accept or Decline to supercede the Revisions decision.
